Figure 1: Growth inhibition of HepG2 cells after the treatment with alantolactone. Cells were cultured for 24 h before drug treatment in 96 well plates. Cells were treated with alantolactone (0, 10, 20, 30, 40, 50, and 60 μM) for 12 h and cell viability was measured by MTT assay. Data are expressed as mean ± SD (). Columns not sharing the same superscript letter differ significantly ().
